Here are several ways to fix error code 0x800F0831 during the installation of SQL Server 2019:

1. Verify system requirements: Ensure your system meets the minimum specifications for SQL Server 2019. This includes checking hardware and software prerequisites such as OS version, CPU, memory, and disk space.
2. Turn off antivirus software: Antivirus programs may disrupt the installation process. Temporarily disable your antivirus software and try reinstalling SQL Server 2019.
